#WPDC - WordPress Docker Compose

Easy WordPress development with Docker and Docker Compose.

With this project you can quickly run the following:

#Requirements

Make sure you have the latest versions of Docker and Docker Compose installed on your machine. The commands in this README use the Compose V2 syntax (docker compose), which ships with Docker Desktop and is available as the docker-compose-plugin package on Linux.

Clone this repository or copy the files from this repository into a new folder. In the docker-compose.yml file you may change the IP address (in case you run multiple containers) or the database from MySQL to MariaDB.

Make sure to add your user to the docker group when using Linux.

#Configuration

Copy the example environment into .env

cp env.example .env

Edit the .env file to change the default IP address, MySQL root password and WordPress database name.

#Installation

Open a terminal and cd to the folder in which docker-compose.yml is saved and run:

docker compose up

This creates two new folders next to your docker-compose.yml file.

  • wp-data – used to store and restore database dumps
  • wp-app – the location of your WordPress application

The containers are now built and running. You should be able to access the WordPress installation with the configured IP in the browser address. By default it is http://127.0.0.1.

For convenience you may add a new entry into your hosts file.

#Usage

#Starting containers

You can start the containers with the up command in daemon mode (by adding -d as an argument) or by using the start command:

docker compose start

#Stopping containers

docker compose stop

#Removing containers

To stop and remove all the containers use thedown command:

docker compose down

Use -v if you need to remove the database volume which is used to persist the database:

docker compose down -v

#Project from existing source

Copy the docker-compose.yml file into a new directory. In the directory you create two folders:

  • wp-data – here you add the database dump
  • wp-app – here you copy your existing WordPress code

You can now use the up command:

docker compose up

This will create the containers and populate the database with the given dump. You may set your host entry and change it in the database, or you simply overwrite it in wp-config.php by adding:

define('WP_HOME','http://wp-app.local');
define('WP_SITEURL','http://wp-app.local');

#Creating database dumps

./export.sh

#Developing a Theme

Configure the volume to load the theme in the container in the docker-compose.yml:

volumes:
  - ./theme-name/trunk/:/var/www/html/wp-content/themes/theme-name

#Developing a Plugin

Configure the volume to load the plugin in the container in the docker-compose.yml:

volumes:
  - ./plugin-name/trunk/:/var/www/html/wp-content/plugins/plugin-name

#WP CLI

The docker compose configuration also provides a service for using the WordPress CLI.

Sample command to install WordPress:

docker compose run --rm wpcli core install --url=http://localhost --title=test --admin_user=admin --admin_email=test@example.com

Or to list installed plugins:

docker compose run --rm wpcli plugin list

For an easier usage you may consider adding an alias for the CLI:

alias wp="docker compose run --rm wpcli"

This way you can use the CLI command above as follows:

wp plugin list

#phpMyAdmin

You can also visit http://127.0.0.1:8080 to access phpMyAdmin after starting the containers.

The default username is root, and the password is the same as supplied in the .env file.

New version available.
